Description of problem:
I use snd_intel_hda with Realtek ALC883 hardware. Playing a (typically Vorbis-encoded) track (although this may be more to do with it being 48k/16-bit) in Audacious, and then using the arrow keys to rapidly skip, causes Pulseaudio to hang leaving the last bit of sound repeatedly playing. Output from a typical Pulseaudio session:
Additional info:N: main.c: Called SUID root and real-time/high-priority scheduling was requested in the configuration. However, we lack the necessary priviliges:
N: main.c: We are not in group 'pulse-rt' and PolicyKit refuse to grant us priviliges. Dropping SUID again.
N: main.c: For enabling real-time scheduling please acquire the appropriate PolicyKit priviliges, or become a member of 'pulse-rt', or increase the RLIMIT_NICE/RLIMIT_RTPRIO resource limits for this user.
W: pid.c: Stale PID file, overwriting.

and so-on. Pulseaudio has to be given SIGKILL to bring this all to an end.
Version-Release number of selected component (if applicable):
pulseaudio-0.9.10-2.fc9.x86_64
kernel-2.6.27.6-43.fc9.x86_64
How reproducible:
Always.
Steps to Reproduce:
1. Start pulseaudio and audacious.
2. Play a vorbis-encoded track.
3. Press left (or right) arrow key repeatedly about a minute in to skip quickly in succession.
Actual results:
Pulse hangs, frame repeats, doesn't respond to control applets. Audacious hangs.
Expected results:
Flawless skipping.
